M EAT-CUTTER.

SPECIFICATION forming part of Letters Patent No. 230,728, dated August 3, 1880,

Application filed April 29, 1880.

To all whom it may concern:

Be it known that I, JOHN B. ADT, of the city of Baltimore and State of Maryland, have invented certain Improvements in Meat-Outters, of which the following is a specification; and I do hereby declare that in the same is contained a full, clear, and exact description of my said invention. reference being had to the accompanying drawings, and to the letters of reference marked thereon.

This invention relates to certain improvements in a machine for cutting into small pieces refuse fatty matter from slaughterhouses, the object being to prepare the said fatty matter for the rendering-tanks used in the manufacture of lard and tallow.

In the further description of my said invention which follows reference is made to the accompanying drawings, formin g a part hereof, and in which- Figure I is a plan of the improved machine. Fig. II is an interior side view of the invention. Figs. III, IV, and V are views of parts of the machine on an enlarged scale.

Similar letters of reference indicate similar parts in all the views.

In the said drawings, A is the frame of the machine. 13 B are circular knives secured to a shaft, a, adapted to revolve in suitable bearings. The edges of the knives, which may be either toothed or plain, enter grooves in a drum. 0, located below the shaft a. as shown in Figs. III and IV of the drawings.

D is an endless apron composed of strips 1) connected by links 0. The endless apron passes over or around two rollers, E and F, and it has such movement as to carry the matter to be out, which is placed on the upper surface of the apron, toward the revoluble knives B.

G is the driving-shaft through which power is applied to the machine, and it is provided with a tight and a loose pulley, represented respectively by (Z and c, and a fiy-wheel, H.

The movement of the driving-shaft G is first communicated to the intermediate shaft, I, by means of the pinion c and wheel f, and then from the intermediate shaft, I, to the shaft K, to which the drum 0 is secured, through the medium of a pinion, g, and wheel L.

The circular knives are operated by means (No model.)

of a wheel, M, on the shaft K, and a smaller wheel, N, on the shaft (1, to which shaft the knives B are fastened.

As before stated, the fat is carried toward the circular knives by the endless apron, and as the fat approaches the said knives it is caught by a series of toothed disks, 0, which derive their motion from the wheel M by means of the wheels i, k, and l, and forced between the knives and the drum 0 and cut into strips. The strips of fat, after leaving the cutting devices described, pass through an aperture, on, in the frame A of the machine, and in this operation they are cut transversely by means of a knife, n, attached to a plate, 0, which has a reciprocating movement across the said aperture.

The plate 0 and its knife receive their movement from a crank, 12, forming a part of the driving-shaft Gr, through the agency of a rod, 1'. (See Fig. III.)

The surfaces of the circular knives are freed from adhering fat by scrapers s projecting from the frame A, and the outer surface and the grooves of the drum are cleansed in a similar manner by means of a part, t, of the frame.

I claim as my invention- 1. In a fat-cutting machine, a series of circular revoluble knives, a revoluble drum having grooves, into which the edges of the said knives project, and mechanism for effecting the joint revolution of the said knives and drum, combined with an endless apron adapted to conduct the fat to be cut to the said cutting devices, substantially as herein specified.

2. In a fat-cutting machine, a series of re voluble circular knives, a revoluble drum having grooves, into which the edge of the said knives project, and an endless apron adapted to carry the material to be cut to the said knives and drum, combined with a series of revoluble toothed disks placed over the said endless apron and adapted to enforce the passage of the said material to the said knives, substantially as herein specified.

JOHN B. ADT.
